Question

Respected All,

 

I am new to .net core and am stuck at one point in my development.

 

I have requirement for developing app using asp.net core mvc, web api with token based google-gmail authentication.

 

I have done coding with simple google authentication but not sure about token based web api development.

 

I have gone through so many article but not found proper flow with my requirements.

 

And also i have to use sqlite db.

 

Please help me out for the solution.

 

 

Thank You.
